CROSS REFERENCE

This application is a continuation of U.S. Non-Provisional patent application Ser. No. 17/713,194, filed on Apr. 4, 2022, and titled “Upgrading Meshnet Connections In A Mesh Network,” the entire contents of which are incorporated herein by reference.

FIELD OF DISCLOSURE

Aspects of the present disclosure generally relate to communications in networks, and more particularly to upgrading meshnet connections in a mesh network.

BACKGROUND

Users may rely on mesh networks (also referred to as “meshnets”) to communicate (e.g., transmit and/or receive) data among a plurality of endpoints (e.g., user devices) via one or more Internet nodes (e.g., bridges, switches, infrastructure devices, etc.). In an example, a mesh network may include a plurality of endpoints communicatively coupled to each other directly or via the one or more Internet nodes. A mesh network in which all endpoints are communicatively coupled to each other may be referred to as a fully connected network. Data transmitted by a first endpoint, from among the plurality of endpoints, may be routed over the Internet via the one or more Internet nodes to a second endpoint from among the plurality of endpoints. Also, data transmitted by the first endpoint may be routed to two or more endpoints from among the plurality of endpoints.

In a mesh network, the plurality of endpoints may cooperate with each other to enable communication of the data among the plurality of endpoints. In an example, one or more of the endpoints may participate in communication of the data. In this way, the mesh network may avoid relying on a given endpoint for communication of the data. Some mesh networks may have the ability to dynamically self-organize and self-configure the plurality of endpoints. This ability may allow such mesh networks to enable dynamic distribution of workloads, particularly in the event that one or more endpoints should fail. Further, installation overhead may be reduced.

SUMMARY

In one aspect, the present disclosure contemplates a method including determining, by a first device in communication with a second device in a mesh network, an optimal midpath node to be utilized for communicating meshnet data between the first device and the second device; and transmitting, by the first device to the second device, coordination information including identification information that identifies the optimal midpath node and timing information that indicates a time associated with connecting with the optimal midpath node to enable utilization of the optimal midpath node for communicating the meshnet data.

In another aspect, the present disclosure contemplates a first device including a memory and a processor configured to: determine, while in communication with a second device in a mesh network, an optimal midpath node to be utilized for communicating meshnet data between the first device and the second device; and transmit, to the second device, coordination information including identification information that identifies the optimal midpath node and timing information that indicates a time associated with connecting with the optimal midpath node to enable utilization of the optimal midpath node for communicating the meshnet data.

In another aspect, the present disclosure contemplates a non-transitory computer readable medium storing instructions, which when executed by a processor associated with a first device, cause the processor to: determine, while in communication with a second device in a mesh network, an optimal midpath node to be utilized for communicating meshnet data between the first device and the second device; and transmit, to the second device, coordination information including identification information that identifies the optimal midpath node and timing information that indicates a time associated with connecting with the optimal midpath node to enable utilization of the optimal midpath node for communicating the meshnet data.

For simplicity, in some instances the same reference numbers are used throughout the drawings to refer to the same or like parts.

FIG. 1 is an illustration of an example 100 associated with upgrading meshnet connections in a mesh network, according to various aspects of the present disclosure. Example 100 shows an architectural depiction of included components. In some aspects, the components may include one or more user devices 102 capable of communicating with a mesh network service provider (MSP) control infrastructure 104 for purposes of obtaining mesh network services. In some aspects, the one or more user devices 102 may communicate with the MSP control infrastructure 104 over a network 118. The MSP control infrastructure 104 may be controlled by a mesh network service provider and may include an application programming interface (API) 106, a user database 108, processing unit 110, and a meshnet database 112. In some aspects, a user device 102 may utilize a processing unit 116 and/or a client application 114, which is provided by the MSP control infrastructure 104, to communicate with the API 106. The API 106 may be capable of communicating with the user database 108 and with the processing unit 110. Additionally, the processing unit 110 may be capable of communicating with the meshnet database 112, which may be capable of storing data associated with providing mesh network services.

The user device 102 may be a physical computing device capable of hosting the client application 114 and of connecting to the network 118. The user device 102 may be, for example, a laptop, a mobile phone, a tablet computer, a desktop computer, a smart device, a router, or the like. In some aspects, the user device 102 may include, for example, Internet-of-Things (IoT) devices such as MSP smart home appliances, smart home security systems, autonomous vehicles, smart health monitors, smart factory equipment, wireless inventory trackers, biometric cyber security scanners, or the like. The network 118 may be any digital telecommunication network that permits several nodes to share and access resources. In some aspects, the network 118 may include one or more of, for example, a local-area network (LAN), a wide-area network (WAN), a campus-area network (CAN), a metropolitan-area network (MAN), a home-area network (HAN), Internet, Intranet, Extranet, and Internetwork.

The MSP control infrastructure 104 may include a combination of hardware and software components that enable provision of mesh network services to the user device 102. The MSP control infrastructure 104 may interface with (the client application on) the user device 102 via the API 106, which may include one or more endpoints to a defined request-response message system. In some aspects, the API 106 may be configured to receive, via the network 118, a connection request from the user device 102 to establish a connection with the MSP control infrastructure 104 for purposes of obtaining the mesh network services. The connection request may include an authentication request to authenticate the user device 102. The API 106 may receive the authentication request and a request for the mesh network services in a single connection request. In some aspects, the API 106 may receive the authentication request and the request for the mesh network services in separate connection requests.

The API 106 may further be configured to handle the connection request by mediating the authentication request. For instance, the API 106 may receive from the user device 102 credentials including, for example, a unique combination of a user ID and password for purposes of authenticating the user device 102. In another example, the credentials may include a unique validation code known to an authentic user. The API 106 may provide the received credentials to the user database 108 for verification.

The user database 108 may include a structured repository of valid credentials belonging to authentic users. In one example, the structured repository may include one or more tables containing valid unique combinations of user IDs and passwords belonging to authentic users. In another example, the structured repository may include one or more tables containing valid unique validation codes associated with authentic users. The mesh network service provider may add or delete such valid unique combinations of user IDs and passwords from the structured repository at any time. Based at least in part on receiving the credentials from the API 106, the user database 108 and a processor (e.g., the processing unit 110 or another local or remote processor) may verify the received credentials by matching the received credentials with the valid credentials stored in the structured repository. In some aspects, the user database 108 and the processor may authenticate the user device 102 when the received credentials match at least one of the valid credentials. In this case, the mesh network service provider may provide mesh network services to the user device 102. When the received credentials fail to match at least one of the valid credentials, the user database 108 and the processor may fail to authenticate the user device 102. In this case, the mesh network service provider may decline to provide mesh network services to the user device 102.

When the user device 102 is authenticated, the user device 102 may initiate a connection and may transmit to the API 106 a request for the mesh network services. The processing unit 110 included in the MSP control infrastructure 104 may be configured to determine a mesh network associated with the user device 102 and/or to identify one or more user devices to be included within the determined mesh network. The processing unit 110 may utilize the API 106 to transmit information associated with the mesh network and/or the identified one or more user devices to the user device 102. The user device 102 may transmit an initiation request to establish secure connections (e.g., encrypted tunnels) with the one or more user devices. In some aspects, the one or more user devices with which the user device 102 establishes the secure connections may also host respective client applications for communicating with the MSP control infrastructure 104 and/or with the user device 102. In some aspects, the processing unit 110 may be a logical unit including a logical component configured to perform complex operations associated with computing, for example, numerical weights related to various factors associated with providing the meshnet services.

One or more components (e.g., API 106, user database 108, processing unit 110, and/or meshnet database 112, processing unit 116) included in the MSP control infrastructure 104 and/or included in the user device 102 may further be associated with a controller/processor, a memory, a communication interface, or a combination thereof (e.g., FIG. 7 ). For instance, the one or more components of the set of components may include or may be included in a controller/processor, a memory, or a combination thereof. In some aspects, the one or more of the components included in the MSP control infrastructure 104 may be separate and distinct from each other. Alternatively, in some aspects, the one or more of the components included in the MSP control infrastructure 104 may be combined with one or more of the other components. In some aspects, the one or more of the components included in the MSP control infrastructure 104 and/or the user device 102 may be local with respect to each other. Alternatively, in some aspects, one or more of the components included in the MSP control infrastructure 104 and/or the user device 102 may be located remotely with respect to one or more of other components included in the MSP control infrastructure 104 and/or the user device 102. Additionally, or alternatively, one or more components of the components included in the MSP control infrastructure 104 and/or the user device 102 may be implemented at least in part as software stored in a memory. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or a processor to perform the functions or operations of the component. Additionally, or alternatively, a set of (one or more) components shown in FIG. 1 may be configured to perform one or more functions described as being performed by another set of components shown in FIG. 1 .

As indicated above, FIG. 1 is provided as an example. Other examples may differ from what is described with regard to FIG. 1 .

Endpoints (e.g., user devices) may rely on a mesh network to communicate (e.g., transmit and/or receive) meshnet data among the endpoints. In example 200 shown in FIG. 2 , the endpoints may include a first user device, a second user device, a third user device, and/or a fourth user device. The meshnet data may be communicated using wired communications and/or wireless communications over a network such as, for example, the Internet. The meshnet data may include any information including digital information such as, for example, documents including data, voice data, image data, signal data, and/or video data. Further, the internal mesh network may be a secure mesh network that may enable the endpoints to communicate the meshnet data in encrypted form via meshnet connections (shown as double-ended arrows in FIG. 2 ).

In some cases, the meshnet connection between, for example, the first user device and the second user device may experience unreliability and/or latency while communicating the meshnet data. The unreliability may be introduced due to, for example, constant variation in an amount of available bandwidth associated with an internet network node (e.g., midpath node) utilized to communicate the meshnet data via the meshnet connection. In an example, when the amount of available bandwidth fails to satisfy a bandwidth threshold (e.g., the available bandwidth is lower than the bandwidth threshold), communication of the meshnet data via the meshnet connection may experience heightened unreliability and/or latency.

To address such unreliability and/or latency, the first user device may search for a first optimal midpath node, located on a meshnet connection path in between the first user device and the second user device (e.g., midpath), for communicating the meshnet data via the meshnet connection. In some aspects, the first optimal midpath node may have an amount of available bandwidth that satisfies the bandwidth threshold (e.g., the available bandwidth is equal to or greater than the bandwidth threshold). To determine or locate the first optimal midpath node, the first user device may determine available bandwidths associated with a plurality of midpath nodes. In an example, the first user device may communicate a ping via a first midpath node and determine a first amount of available bandwidth associated with the first midpath node based at least in part on a time associated with communication of the ping with a destination node, via a second midpath node and determine a second amount of available bandwidth associated with the second midpath node based at least in part on a time associated with communication of the ping with a destination node, via a third midpath node and determine a third amount of available bandwidth associated with the third midpath node based at least in part on a time associated with communication of the ping with a destination node, and so on. The first user device may select the midpath node associated with the highest amount of available bandwidth as the first optimal midpath node. Based at least in part on determining the first optimal midpath node, the first user device may determine that the meshnet connection between the first user device and the second user device is to utilize the first optimal midpath node to communicate the meshnet data.

The second user device may also determine a second optimal midpath node similarly and or analogously in a manner as discussed above with respect to the first user device. Based at least in part on determining the second optimal midpath node, the second user device may determine that the meshnet connection between the first user device and the second user device is to utilize the second optimal midpath node to communicate the meshnet data.

In some cases, the first optimal midpath node may be different from the second optimal midpath node. Additionally, the first user device may be unaware of the second optimal midpath node. As a result, although the first user device may be able to utilize the first optimal midpath node, the second user device may be unable to use the first optimal midpath node. Similarly, the second user device may be unaware of the first optimal midpath node. As a result, although the second user device may be able to use the second optimal midpath node, the first user device may be unable to use the second optimal midpath node.

Additionally, although the first optimal midpath node may satisfy the bandwidth threshold with respect to communication associated with the first user device, the first optimal midpath node may fail to satisfy the bandwidth threshold with respect to communication associated with the second user device. In an example, the first optimal midpath node may provide optimal bandwidth to the first user device and, due to existing environmental and network conditions, may fail to provide the optimal bandwidth to the second user device. Similarly, although the second optimal midpath node may satisfy the bandwidth threshold with respect to communication associated with the second user device, the second optimal midpath node may fail to satisfy the bandwidth threshold with respect to communication associated with the first user device. In an example, the second optimal midpath node may provide optimal bandwidth to the second user device and, due to existing environmental and network conditions, may fail to provide the optimal bandwidth to the first user device.

For at least the above reasons, the single meshnet connection may be unable to utilize the first optimal midpath node and/or the second optimal midpath node. Further, because a single meshnet connection may be permitted between the first user device and the second user device at a given time, the first user device and the second user device may be unable to coordinate establishment of the meshnet connection that utilizes the first optimal midpath node and/or the second optimal midpath node to communicate the meshnet data.

In this case, the meshnet connection between the first user device and the second user device may continue to experience unreliability and/or latency, due to which the first user device and/or the second user device may fail to receive the meshnet data. As a result, communication between the first user device and the second user device may be interrupted. Further, the first user device and/or the second user device may retransmit the meshnet data to ensure receipt thereof by the other user device. Such transmission and retransmission of communications may inefficiently consume user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) that can otherwise be utilized to perform suitable tasks associated with the mesh network. The above discussion with respect to the first user device and the second user device may also apply to the one or more other user devices in the mesh network.

Various aspects of systems and techniques discussed in the present disclosure enable upgrading meshnet connections in a mesh network. In some aspects, an MSP control infrastructure may provide the mesh network to enable endpoints to securely communicate meshnet data. Further, the MSP control infrastructure may provide the endpoints with respective client applications to communicate with the MSP control infrastructure, and/or to communicate with each other for setting up respective meshnet connections to be utilized for communicating meshnet data in the mesh network, and/or to communicate the meshnet data (e.g., meshnet communications) with each other over the respective meshnet connections. The MSP control infrastructure and the respective client applications may also enable upgrading meshnet connections in a mesh network. In some aspects, a first user device may upgrade an existing meshnet connection with a second user device based at least in part on determining an optimal midpath node to be utilized to communicate the meshnet data. The first user device may transmit, to the second user device, coordination information identifying the optimal midpath node. In some aspects, such transmission of identification information may be via an independent connection that is separate from the existing meshnet connection. The coordination information may also indicate a time associated with establishing a new meshnet connection that utilizes the optimal midpath node. Based at least in part on the coordination information, the first user device and the second user device may release the existing meshnet connection and may establish the new meshnet connection that utilizes the optimal midpath node having an amount of available bandwidth that satisfies a bandwidth threshold and/or the latency threshold. In this way, the first user device and/or the second user device may alleviate any unreliability and/or latency observed while communicating via the existing meshnet connection, and communication between the first user device and the second user device may continue uninterrupted via the new meshnet connection. Further, instances of inefficient transmissions and retransmissions of communications the first user device and/or the second user device may be mitigated. As a result, the MSP control infrastructure and the respective client applications may enable efficient utilization of user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) for performing suitable tasks associated with the mesh network.

In some aspects, a processor (e.g., processing unit 116, processor 720) associated with a user device may determine, while in communication with a second device in a mesh network, an optimal midpath node to be utilized for communicating meshnet data between the first device and the second device; and transmit, to the second device, coordination information including identification information that identifies the optimal midpath node and timing information that indicates a time associated with connecting with the optimal midpath node to enable utilization of the optimal midpath node for communicating the meshnet data.

As indicated above, FIG. 2 is provided as an example. Other examples may differ from what is described with regard to FIG. 2 .

FIG. 3 is an illustration of an example flow 300 associated with upgrading meshnet connections in a mesh network, according to various aspects of the present disclosure. The example flow 300 may include a first user device (e.g., first endpoint), MSP control infrastructure 104, and a second user device (e.g., second endpoint) in communication with each other. The first user device and the second user device may be similar to a user device 102 discussed above with respect to FIG. 1 . In some aspects, the first user device and the second user device may be associated with a single account registered with the MSP control infrastructure 104. In some aspects, the first user device and the second user device may be associated with different accounts registered with the MSP control infrastructure 104. In some aspects, the first user device and the second user device may be located locally (e.g., in the same room, in the same building, etc.). In some aspects, the first user device and the second user device may be located remotely (e.g., in different buildings, in different cities, in different states, in different countries, etc.) with respect to each other.

The first user device may install a first client application (e.g., client application 114) and the second user device may install a second client application (e.g., client application 114), the first client application and the second client application being associated with (e.g., provided by) the MSP control infrastructure 104. The first user device and the second user device may use the respective client applications to communicate with an application programming interface (API) and/or a processor (e.g., processing unit 110, processor 720) associated with the MSP control infrastructure 104. In some aspects, the first user device, the MSP control infrastructure 104, and the second user device may communicate with each other over a network (e.g., network 118). As discussed elsewhere herein, the MSP control infrastructure 104 may enable the first user device and/or the second user device to obtain the mesh network services.

In some aspects, the client applications may enable the user devices to receive information to be processed by the client applications and/or by the MSP control infrastructure 104. Each of the client applications may include respective graphical user interfaces to receive the information via local input interfaces (e.g., touch screen, keyboard, mouse, pointer, etc.) associated with the user devices. The information may be received via text input or via a selection from among a plurality of options (e.g., pull down menu, etc.). In some aspects, the first client application and/or the second client application may activate and/or enable, at a time associated with the registration (e.g., after the registration), the graphical interface for receiving the information. For instance, the first client application (or the second client application) may cause a screen (e.g., local screen) associated with the first user device (or the second user device) to display, for example, a pop-up message to request entry of the information. Further, the client applications may enable transmission of at least a portion of the information to the MSP control infrastructure 104. In some aspects, the first client application may utilize a first processing unit (e.g., processing unit 116, processor 720) associated with the first user device to perform processes/operations associated with obtaining the mesh network services and the second application may utilize a second processing unit (e.g., processing unit 116, processor 720) associated with the second user device to perform processes/operations associated with obtaining the mesh network services.

Although only two user devices (e.g., endpoints) are shown in FIG. 3 , the present disclosure contemplates the mesh network to include any number of user devices that perform the processes discussed herein in a similar and/or analogous manner. For instance, the mesh network may include a third user device and a fourth user device, as discussed above with respect to FIG. 2 , that perform the processes discussed herein in a similar and/or analogous manner. Further, user devices may leave or join the mesh network in an ad-hoc manner.

As shown by reference numeral 305, the first user device may register an account with the MSP control infrastructure 104. In some aspects, during the registration, the first user device may provide registration information such as, for example, identity of an owner of the first user device, a phone number associated with the first user device, an email address associated with the first user device, or the like. In some aspects, the first user device may set up an access system including login information (e.g., access information) such as, for example, username, password, or the like to subsequently gain access to the registered account. In some aspects, the first user device may share the login information with other user devices (e.g., second user device) associated with the first user device to enable the other user devices to utilize the login information to gain access to the MSP control infrastructure 104 via the registered account. In some aspects, a given user device may be associated with the first user device because the given user device may be available to a user/owner of the first user device. In some aspects, when the second user device is not associated with the registered account associated with the first user device, the second user device may register a different account with the MSP control infrastructure 104.

In some aspects, the first user device and the second user device may utilize the login information to access the registered account/accounts to communicate with the MSP control infrastructure 104. As shown by reference numeral 310, based at least in part on the first user device and the second user device accessing the registered account/accounts to communicate with the MSP control infrastructure 104, the MSP control infrastructure 104 may transmit, and the first client application and the second client application may receive, MSP access information. In some aspects, the MSP access information may include UDP access information. The UDP access information may include information regarding an infrastructure UDP IP address and an infrastructure UDP port associated with the MSP control infrastructure 104. The MSP control infrastructure 104 may utilize the infrastructure UDP IP address and the infrastructure UDP port to communicate utilizing the UDP. In some aspects, the first user device and the second user device may utilize the infrastructure UDP IP address and the infrastructure UDP port to communicate with the MSP control infrastructure 104 regarding the mesh network. Further, the first client application and the second client application may obtain from, for example, a domain name services (DNS) server, transmission control protocol (TCP) access information associated with the MSP control infrastructure 104. Such TCP access information may include information regarding an infrastructure TCP IP address and an infrastructure TCP port associated with the MSP control infrastructure 104. The MSP control infrastructure 104 may utilize the infrastructure TCP IP address and the infrastructure TCP port to communicate utilizing the TCP.

As shown by reference numeral 315, the first client application and the second client application may determine information based at least in part on the registration of the account/accounts with the MSP control infrastructure 104. In an example, the first client application may determine an asymmetric first assigned key pair associated with the first user device. The first assigned key pair may be unique to the first user device and may include a first assigned public key and a first assigned private key. In this way, the first assigned public key and the first assigned private key may be device-specific and may be associated with the registered account. In some aspects, the first assigned public key and the first assigned private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the first assigned public key may be decrypted by utilizing the first assigned private key.

Similarly, the second client application may determine an asymmetric second assigned key pair associated with the second user device. The second assigned key pair may be unique to the second user device and may include a second assigned public key and a second assigned private key. In this way, the second assigned public key and the second assigned private key may be device-specific and may be associated with the registered account. In some aspects, the second assigned public key and the second assigned private key may be associated with each other via, for example, a mathematical function. As a result, data encrypted using the second assigned public key may be decrypted by utilizing the second assigned private key.

As shown by reference numeral 320, the client applications may transmit, and the MSP control infrastructure 104 may receive, at least a portion of the information determined by the client applications. For instance, the first client application may transmit, for example, the first assigned public key to the MSP control infrastructure 104, and the second client application may transmit, for example, the second assigned public key to the MSP control infrastructure 104. The MSP control infrastructure 104 may store and correlate the received information in association with the registered account and/or with the respective user devices. In an example, the MSP control infrastructure 104 may store and correlate the first assigned public key in association with the registered account and the first user device, and may store and correlate the second assigned public key in association with the registered account and the second user device. In some aspects, the first client application and the second client application may utilize the infrastructure TCP IP address and the infrastructure TCP port to transmit the first assigned public key and the second assigned public key to the MSP control infrastructure 104 via the TCP.

Further, as shown by reference numeral 325, the MSP control infrastructure 104 may determine that the first user device and the second user device are to be included in the same mesh network. In some aspects, when the first user device and the second user device are associated with the same registered account, the MSP control infrastructure 104 may make such a determination regarding the secure mesh network based at least in part on determining that the first user device and the second user device are communicating with the MSP control infrastructure 104 by utilizing the login information associated with the same registered account. In some aspects, when the first user device and the second user device are associated with different registered accounts, the MSP control infrastructure 104 may make such a determination regarding the secure mesh network based at least in part on the first user device (and/or the second user device) providing information indicating that the first user device and the second user device are to be included in the same mesh network. Such information may include, for example, identification information (e.g., type of device, user name, email address, etc.) associated with the second user device (or the first user device), the second IP address (or the first IP address), or the like.

Based at least in part on determining that the first user device and the second user device are to be included in the same mesh network, as shown by reference numeral 330, the MSP control infrastructure 104 may determine meshnet IP addresses for the first user device and for the second user device. In an example, the MSP control infrastructure 104 may determine a first meshnet IP address associated with the first user device and a second meshnet IP address associated with the second user device. The first client application and/or another application installed on the first user device and/or the operating system associated with the first user device may utilize the first meshnet IP address and/or the first local meshnet port to communicate data with the endpoints over meshnet connections in the mesh network and the second user device may utilize the second meshnet IP address and/or the second local meshnet port to communicate data with the endpoints over the meshnet connections in the mesh network. In an example, with respect to communication between the first user device and the second user device, the first user device may determine a first meshnet IP packet indicating the first meshnet IP address as a source address, the first local meshnet port as a source port, the second meshnet IP address as a destination address, and the second local meshnet port as a destination port. The first user device may encrypt and encapsulate the first meshnet IP packet within a payload of a transmitted UDP IP packet. The second user device may receive the UDP IP packet, may decrypt the first meshnet IP packet, and may route the first meshnet IP packet to the second local meshnet port. Similarly, the second user device may determine a second meshnet IP packet indicating the second meshnet IP address as a source address, the second local meshnet port as a source port, the first meshnet IP address as a destination address, and the first local meshnet port as a destination port. The second user device may encrypt and encapsulate the second meshnet IP packet within a payload of a transmitted UDP IP packet. The first user device may receive the UDP IP packet, may decrypt the first meshnet IP packet, and may route the second meshnet IP packet to the first local meshnet port. The MSP control infrastructure 104 may determine the first meshnet IP address and the second meshnet IP address from, for example, a pool of reserved IP addresses included in a subnet associated with an internal network of the ISP.

As shown by reference numeral 335, the first user device and the second user device may transmit, and the MSP control infrastructure 104 may receive, respective binding requests. In some aspects, the first user device may transmit the first binding request to the MSP control infrastructure 104 using the UDP by utilizing the UDP access information received from the MSP control infrastructure 104 (e.g., block 320). In this case, the first user device may transmit a first binding request to the MSP control infrastructure 104 to request the MSP control infrastructure 104 to determine a first public UDP IP address (e.g., communication address) and/or a first public UDP port (e.g., communication port) associated with the first user device. As discussed below in further detail, the first public UDP IP address and/or the first public UDP port are to be utilized by the second user device to communicate with the first user device in the mesh network. Similarly, the second user device may transmit the second binding request to the MSP control infrastructure 104 using the UDP by utilizing the UDP access information received from the MSP control infrastructure 104 (e.g., block 320). In this case, the second user device may transmit a second binding request to the MSP control infrastructure 104 to request the MSP control infrastructure 104 to determine a second public UDP IP address (e.g., communication address) and/or a second public UDP port (e.g., communication port) associated with the second user device. As discussed below in further detail, the second UDP IP address and/or the second UDP port are to be utilized by the first user device to communicate with the second user device in the mesh network.

In some aspects, the first public UDP IP address and/or the first public UDP port may be determined by a first NAT device (e.g., a router) responsible for managing operation of the first user device in a first local network. In an example, the first NAT device may translate a first local UDP IP address and/or a first local UDP port associated with the first user device to the first public UDP IP address and/or the first public UDP port that the first user device utilizes to communicate (e.g., transmit and/or receive) over the Internet using the UDP. Similarly, the second public UDP IP address and/or the second public UDP port may be determined by a second NAT device responsible for managing operation of the second user device in a second local network. In an example, the second NAT device may translate a second local UDP IP address and/or a second local UDP port associated with the second user device to the second public UDP IP address and/or the second public UDP port that the second user device utilized to communicate (e.g., transmit and/or receive) over the Internet using the UDP.

Based at least in part on receiving the respective binding requests, as shown by reference numeral 340, the MSP control infrastructure 104 may determine public UDP IP addresses and/or public UDP ports associated with the first user device and the second user device. In an example, based at least in part on receiving the first binding request, the MSP control infrastructure 104 may determine the first public UDP IP address and/or the first public UDP port associated with the first user device. In some aspects, the MSP control infrastructure 104 may determine the first public UDP IP address and/or the first public UDP port based at least in part on analyzing the UDP communication (e.g., UDP IP packet) including the first binding request received from the first user device. The UDP communication may include, for example, a header that indicates the first public UDP IP address as a source UDP IP address and/or the first public UDP port as a source UDP port associated with the first user device. Further, the MSP control infrastructure 104 may store and correlate the first public UDP IP address and/or the first UDP port in association with the first user device in, for example, the meshnet database 112. Similarly, based at least in part on receiving the second binding request, the MSP control infrastructure 104 may determine the second public UDP IP address and/or the second public UDP port associated with the second user device. In some aspects, the MSP control infrastructure 104 may determine the second public UDP IP address and/or the second public UDP port based at least in part on analyzing the UDP communication (e.g., UDP IP packet) including the second binding request received from the second user device. The UDP communication may include, for example, a header that indicates the second public UDP IP address as a source UDP IP address and/or the second public UDP port as a source UDP port associated with the second user device. Further, the MSP control infrastructure 104 may store and correlate the second public UDP IP address and/or the second public UDP port in association with the second user device in, for example, the meshnet database 112.

Based at least in part on determining the public UDP IP addresses and/or the public UDP ports, as shown by reference numeral 345, the MSP control infrastructure 104 may transmit, and the first client application and the second client application may receive, communication information. In an example, the MSP control infrastructure 104 may transmit, and the first client application may receive, first communication information including the first meshnet IP address associated with the first user device, the second meshnet IP address associated with the second user device, the second public UDP IP address and/or the second public UDP port associated with the second user device, and the second public key associated with the second user device. Similarly, the MSP control infrastructure 104 may transmit, and the second client application may receive, second communication information including the first public UDP IP address and/or the first public UDP port associated with the first user device, the first public key associated with the first user device, the first meshnet IP address associated with the first user device, and the second meshnet IP address associated with the second user device. As discussed below in further detail, the above transmission of communication information may enable the first user device and the second user device to communicate securely and privately in the mesh network.

As shown by reference numeral 350, the first client application and the second client application may communicate with each other directly to set up a meshnet connection (e.g., an encrypted tunnel) for communicating encrypted data in the mesh network. To set up the meshnet connection, the first client application may utilize the second assigned public key and/or the second public IP address (e.g., second UDP IP address) to securely (e.g., in encrypted form) communicate with the second client application, and the second client application may utilize the first assigned public key and/or the first public IP address (e.g., first UDP IP address) to securely communicate with the first client application. In some aspects, the first client application and the second client application may communicate to securely/privately negotiate parameters (e.g., a symmetric encryption/decryption key) associated with the meshnet connection. In some aspects, the parameters may be randomly generated to provide optimized security to the communications. In an example, the first client application and the second client application may privately negotiate a randomly generated symmetric key that is to be utilized by the first client application and the second client application for encrypting and decrypting data communicated via the meshnet connection. The randomly generated symmetric key may be determined based at least in part on any combination of the first public key, the second public key, and/or randomly generated numbers. Additionally, the first client application and the second client application may utilize a secure protocol (e.g., Wireguard, IP sec, etc.) to communicate the data via the meshnet connection.

Additionally, or alternatively, the first client application and the second client application may communicate with each other indirectly via, for example, a relay device (e.g., a relay server) to set up the meshnet connection. In an example, the first client application may provide the first assigned public key to a relay server, which may store an association of the first assigned public key with the first client application. In some aspects, the association may include an association between the first assigned public key and a first communication connection between the relay server and the first client application. Similarly, the second client application may provide the second assigned public key to the relay server, which may store an association of the second assigned public key with the second client application. In some aspects, the association may include an association between the second assigned public key and a second communication connection between the relay server and the first client application. The relay server may rely on the stored associations of public keys and client applications to determine a destination of a received message. In some aspects, the relay server may include a network of relay servers that enable the first client application and the second client application to communicate with each other. In this case, the first client application and the second client application may provide the respective assigned public keys to different relay servers included within the network of relay servers.

In some aspects, the first client application may transmit, to the relay server, a first message that is to be delivered to the second client application. Along with the first message, the first client application may transmit the second assigned public key. Further, the first client application may encrypt the first message utilizing the second assigned public key. In some aspects, the first client application may encrypt the first message based at least in part on utilizing the negotiated randomly generated symmetric key. Based at least in part on receiving the encrypted first message and the second assigned public key, the relay server may determine from stored associations that the second assigned public key is associated with the second client application. As a result, the relay server may determine that the first message is to be relayed (e.g., transmitted) to the second client application. Similarly, the second client application may transmit, to the relay server, a second message that is to be delivered to the first client application. Along with the second message, the second client application may transmit the first assigned public key. Further, the second client application may encrypt the second message utilizing the first assigned public key. In some aspects, the second client application may encrypt the second message based at least in part on utilizing the negotiated randomly generated symmetric key. Based at least in part on receiving the encrypted second message and the first assigned public key, the relay server may determine from stored associations that the first assigned public key is associated with the first client application. As a result, the relay server may determine that the second message is to be relayed (e.g., transmitted) to the first client application. In this way, the relay server may enable the first client application and the second client application to communicate with each other to set up the meshnet connection.

Based at least in part on setting up the meshnet connection, the first client application and the second client application may begin communicating encrypted data via the meshnet connection based at least in part on utilizing the negotiated parameters and the secure protocol. In a similar and/or analogous manner, the first client application may set up meshnet connections with a third client application installed in the third client application and with a fourth client application associated with the fourth client application. Also, in a similar and/or analogous manner, the second client application may set up meshnet connections with the first client application, the third client application, and the fourth client application. Further, in a similar and/or analogous manner, the third client application may set up meshnet connections with the first client application, the second client application, and the fourth client application. Finally, in a similar and/or analogous manner, the fourth client application may set up meshnet connections with the first client application, the second client application, and the third client application. Additional client applications that enter the mesh network may also set up meshnet connections with the other client applications included in the mesh network.

Further, based at least in part on setting up the meshnet connection, as shown by reference numeral 355, the first user device and the second user device may enable upgrading of meshnet connections in the mesh network. In some aspects, the first user device and the second user device may upgrade an existing meshnet connection by establishing a new meshnet connection based at least in part on observing unreliability and/or latency while communicating the meshnet data via the existing meshnet connection.

In some aspects, the first client application may identify candidate midpath nodes that may be utilized by the new meshnet connection for communicating the meshnet data. In some aspects, the candidate midpath nodes may include devices included in, for example, a local area network (LAN) network associated with the first user device. Such a LAN network may include a home network, an office network, a school network, a peer-to-peer network, a wireless LAN network (e.g., Wi-Fi), or the like as the candidate midpath nodes. In some aspects, the candidate midpath nodes may include client devices that share a given NAT device with the first user device. In some cases, the client devices and the first user device may be serviced by the given NAT device. Some examples of the candidate midpath nodes may include network devices such as, for example, another user device (e.g., a laptop, a desktop, a tablet, etc.) or a smart device (e.g., smart phone, smart watch, smart ring, etc.) or a network device (e.g., switch, router, access point, etc.) associated with the first user device.

Based at least in part on identifying the candidate midpath nodes, the first client application may determine an optimal midpath node from among the candidate midpath nodes. In some aspects, the optimal midpath node may be an improvement over an existing midpath node being utilized to communicate the meshnet data via the existing meshnet connection. In some aspects, the optimal midpath node may have an amount of available bandwidth that satisfies a bandwidth threshold such that the observed unreliability and/or latency associated with communicating the meshnet data is optimally reduced. To determine the optimal midpath node, the first client application may determine available bandwidths and/or latencies associated with each of the candidate midpath nodes.

To determine the available bandwidths and/or latencies, the first client application may communicate a ping to and from a destination device via each of the candidate midpath nodes. In an example, the first client application may communicate the ping to and from the destination device via a first candidate midpath node and determine a first amount of available bandwidth and/or latency associated with the first candidate midpath node, via a second candidate midpath node and determine a second amount of available bandwidth and/or latency associated with the second candidate midpath node, via a third candidate midpath node and determine a third amount of available bandwidth and/or latency associated with the third candidate midpath node, and so on. In some aspects, the destination device may include the second user device. Based at least in part on determining the available bandwidths and/or latencies, the first client application may compare the determined available bandwidths and/or latencies with each other and select the candidate midpath node that is associated with the highest amount of available bandwidth and/or latency as the optimal midpath node. In some aspects, the highest amount of available bandwidth may satisfy a bandwidth threshold (e.g., the highest amount of available bandwidth is equal to or greater than the bandwidth threshold). The bandwidth threshold may be associated with a predetermined amount of improvement over the observed amount of available bandwidth. In some aspects, the highest amount of latency may fail to satisfy a latency threshold (e.g., the highest amount of latency is lower than the latency threshold). The latency threshold may be associated with a predetermined amount of improvement over the observed latency. Based at least in part on determining the optimal midpath node, the first client application may determine that the new meshnet connection that utilizes the optimal midpath node is to be established between the first user device and the second user device for communicating the meshnet data.

Further, the first client application may transmit coordination information to the second user device. In some aspects, the first client may transmit the coordination information via a relay connection. In an example, the first user device and the second user device may be associated with a relay server. The first client application may transmit, to the relay server, a coordination message including the coordination information that is to be delivered to the second user device. Along with the coordination message, the first client application may transmit the second assigned public key. Further, the first client application may encrypt the coordination message utilizing the second assigned public key. In some aspects, the first client application may encrypt the coordination message based at least in part on utilizing the negotiated randomly generated symmetric key negotiated between the first user device and the second user device. Based at least in part on receiving the encrypted coordination message and the second assigned public key, the relay server may determine from stored associations that the second assigned public key is associated with the second user device. As a result, the relay server may determine that the coordination message is to be relayed (e.g., transmitted) to the second user device. The second user device may decrypt the coordination message utilizing the second assigned private key to receive the coordination information.

The coordination information may include identification information and/or timing information. The identification information may identify the optimal midpath node. In some aspects, the identification information may include, for example, a public IP address associated with the optimal midpath node. The second client application may utilize the identification information to access and/or connect with the optimal midpath node, thereby allowing the second user device to establish the new meshnet connection with the first user device based at least in part on utilizing the optimal midpath node.

Further, the timing information may indicate a connection time at which the first user device and the second user device are to substantially access and/or connect with the optimal midpath node to establish the new meshnet connection. In some aspects, the first user device and the second user device may coordinate access/connection with the optimal midpath node at substantially the connection time to establish the new meshnet connection. In some aspects, the connection time may indicate a duration and/or an interval of time during which the first user device and the second user device may access and/or connect with the optimal midpath node. In some aspects, the connection time may be indicated via a timer. For instance, the timer may start running at communication of the timing information and the connection time may occur at an expiration of the timer.

Based at least in part on communicating (e.g., transmitting and/or receiving) the coordination information, the first user device and the second user device may utilize the identification information to access and/or connect with the optimal midpath node at substantially the connection time to enable the first user device and the second user device to establish the new meshnet connection, which utilizes the optimal midpath node. In some aspects, the first user device and the second user device may access and/or connect with the optimal midpath node by communicating connection information to establish the access and/or connection with the optimal midpath node. In this case, the first user device and the second user device may release the existing meshnet connection because, at a given time, a single meshnet connection may be permitted between the first user device and the second user device. Based at least in part on establishing the new meshnet connection, the first user device and the second user device may utilize the optimal midpath node to communicate the meshnet data.

Because the new meshnet connection utilizes the optimal midpath node to communicate the meshnet data, the first user device and the second user device may observe optimally reduced unreliability and/or latency, thereby improving communication between the first user device and the second user device. The first user device may periodically determine optimal midpath nodes to enable periodic optimal reduction in observed unreliability and/or latency, as discussed herein. As a result, the first user device may enable periodic upgrading of the meshnet connections.

In some aspects, the other user devices (e.g., second user device, third user device, fourth user device, etc.) included in the mesh network may operate to upgrade meshnet connections in a similar and/or analogous manner as discussed herein with respect to the first user device. For instance, the other user devices in the mesh network may, among other things, determine an optimal midpath node, may determine and transmit coordination information to identify the optimal midpath node and to indicate a connection time, and may establish a new meshnet connection based at least in part on the coordination information, as discussed herein. Additional user devices that enter the mesh network may also upgrade meshnet connections, as discussed herein.

In this way, user devices in a mesh network may alleviate any unreliability and/or latency observed while communicating meshnet data via existing meshnet connections, and communication between the user devices may continue uninterrupted via new meshnet connections. Further, instances of inefficient transmissions and retransmissions of communications by the user devices may be mitigated. As a result, the MSP control infrastructure and the respective client applications may enable efficient utilization of user device resources (e.g., processing resources, memory resources, power consumption resources, battery life, or the like) and network resources (computational resources, network bandwidth, management resources, processing resources, memory resources, or the like) for performing suitable tasks associated with the mesh network.

The example devices 700 may include a universal bus 710 communicatively coupling a processor 720, a memory 730, a storage component 740, an input component 750, an output component 760, and a communication interface 770.

Bus 710 may include a component that permits communication among multiple components of a device 700. Processor 720 may be implemented in hardware, firmware, and/or a combination of hardware and software. Processor 720 may take the form of a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), a microprocessor, a microcontroller, a digital signal processor (DSP), a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or another type of processing component. In some aspects, processor 720 may include one or more processors capable of being programmed to perform a function. Memory 730 may include a random access memory (RAM), a read only memory (ROM), and/or another type of dynamic or static storage device (e.g., a flash memory, a magnetic memory, and/or an optical memory) that stores information and/or instructions for use by processor 720.

Storage component 740 may store information and/or software related to the operation and use of a device 700. For example, storage component 740 may include a hard disk (e.g., a magnetic disk, an optical disk, and/or a magneto-optic disk), a solid state drive (SSD), a compact disc (CD), a digital versatile disc (DVD), a floppy disk, a cartridge, a magnetic tape, and/or another type of non-transitory computer-readable medium, along with a corresponding drive.

Input component 750 may include a component that permits a device 700 to receive information, such as via user input (e.g., a touch screen display, a keyboard, a keypad, a mouse, a button, a switch, and/or a microphone). Additionally, or alternatively, input component 750 may include a component for determining location (e.g., a global positioning system (GPS) component) and/or a sensor (e.g., an accelerometer, a gyroscope, an actuator, another type of positional or environmental sensor, and/or the like). Output component 760 may include a component that provides output information from device 700 (via, for example, a display, a speaker, a haptic feedback component, an audio or visual indicator, and/or the like).

Communication interface 770 may include a transceiver-like component (e.g., a transceiver, a separate receiver, a separate transmitter, and/or the like) that enables a device 700 to communicate with other devices, such as via a wired connection, a wireless connection, or a combination of wired and wireless connections. Communication interface 770 may permit device 700 to receive information from another device and/or provide information to another device. For example, communication interface 770 may include an Ethernet interface, an optical interface, a coaxial interface, an infrared interface, a radio frequency (RF) interface, a universal serial bus (USB) interface, a Wi-Fi interface, a cellular network interface, and/or the like.

A device 700 may perform one or more processes described elsewhere herein. A device 700 may perform these processes based on processor 720 executing software instructions stored by a non-transitory computer-readable medium, such as memory 730 and/or storage component 740. As used herein, the term “computer-readable medium” may refer to a non-transitory memory device. A memory device may include memory space within a single physical storage device or memory space spread across multiple physical storage devices.

Software instructions may be read into memory 730 and/or storage component 740 from another computer-readable medium or from another device via communication interface 770. When executed, software instructions stored in memory 730 and/or storage component 740 may cause processor 720 to perform one or more processes described elsewhere herein. Additionally, or alternatively, hardware circuitry may be used in place of or in combination with software instructions to perform one or more processes described elsewhere herein. Thus, implementations described herein are not limited to any specific combination of hardware circuitry and software.

The quantity and arrangement of components shown in FIG. 7 are provided as an example. In practice, a device 700 may include additional components, fewer components, different components, or differently arranged components than those shown in FIG. 7 . Additionally, or alternatively, a set of components (e.g., one or more components) of a device 700 may perform one or more functions described as being performed by another set of components of a device 700.

As indicated above, FIG. 7 is provided as an example. Other examples may differ from what is described with regard to FIG. 7 .

Persons of ordinary skill in the art will appreciate that the aspects encompassed by the present disclosure are not limited to the particular exemplary aspects described herein. In that regard, although illustrative aspects have been shown and described, a wide range of modification, change, and substitution is contemplated in the foregoing disclosure. It is understood that such variations may be made to the aspects without departing from the scope of the present disclosure. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the present disclosure.

The foregoing disclosure provides illustration and description, but is not intended to be exhaustive or to limit the aspects to the precise form disclosed. Modifications and variations may be made in light of the above disclosure or may be acquired from practice of the aspects.

As used herein, the term “component” or “device” is intended to be broadly construed as hardware, firmware, or a combination of hardware and software. As used herein, a processor is implemented in hardware, firmware, or a combination of hardware and software.

As used herein, satisfying a threshold may, depending on the context, refer to a value being greater than the threshold, greater than or equal to the threshold, less than the threshold, less than or equal to the threshold, equal to the threshold, or not equal to the threshold, among other examples, or combinations thereof.

It will be apparent that systems or methods described herein may be implemented in different forms of hardware, firmware, or a combination of hardware and software. The actual specialized control hardware or software code used to implement these systems or methods is not limiting of the aspects. Thus, the operation and behavior of the systems or methods were described herein without reference to specific software code—it being understood that software and hardware can be designed to implement the systems or methods based, at least in part, on the description herein.

Even though particular combinations of features are recited in the claims or disclosed in the specification, these combinations are not intended to limit the disclosure of various aspects. In fact, many of these features may be combined in ways not specifically recited in the claims or disclosed in the specification. Although each dependent claim listed below may directly depend on only one claim, the disclosure of various aspects includes each dependent claim in combination with every other claim in the claim set. A phrase referring to “at least one of” a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover a, b, c, a-b, a-c, b-c, and a-b-c, as well as any combination with multiples of the same element (for example, a-a, a-a-a, a-a-b, a-a-c, a-b-b, a-c-c, b-b, b-b-b, b-b-c, c-c, and c-c-c or any other ordering of a, b, and c).

No element, act, or instruction used herein should be construed as critical or essential unless explicitly described as such.
